One advantage of studying history is to explain present practice or at least to help place current phenomena in perspective. This paper seeks to explore two related themes which have proved problematic from the earliest times of company auditing in the UK: the nature of the auditor's responsibility; and the public's perception of his role. The conventional view is that auditors were initially concerned mainly with fraud detection, and that it was not until the 1930s that greater emphasis was devoted to the verification of financial statements. This study suggests that statement verification was the primary audit concern in relation to public companies as early as the 1830s, though we acknowledge that later in the century more emphasis was placed on fraud detection. We therefore see the current debate over the auditor's responsibility as merely the latest movement in a continuing and fluctuating theme. We also show that the profession has encountered great difficulty in reconciling public expectations with the practicalities of auditing. General confusion over the role of the auditor has existed to such an extent that it has been difficult even for the profession to reach agreement on the main purpose of company auditing, and the message to be sent to the investing public. In these endeavours, the accounting profession was at the same time both helped and hindered by legal developments.  相似文献

The paper extends the findings of the Coe and Helpman (Eur Econ Rev 39(5):859-887, 1995) model of R&D spillovers by considering foreign direct investment (FDI) as a channel for knowledge spillovers in addition to imports. Deeper insights on the issue are provided by examining the inter-relationship between knowledge spillovers from imports and inward FDI. Furthermore, human capital is added to the discussion as one of the appropriability factors for knowledge spillovers, with special focus on its quality-content, using journal publications and patent applications. Applying cointegration estimation method on 20 European countries from 1995 to 2010, the direct effects of FDI-related as well as import-related spillovers on domestic productivity are confirmed. Furthermore, a strong complementary relationship is found between knowledge spillovers through the channels of imports and inward FDI. When considering quality-adjusted human capital, countries with better human capital are found to benefit not only from direct productivity effects, but also from absorption and transmission of international knowledge spillovers through imports and inward FDI. Finally, technological distance with the frontier does not appear to play a role in the absorption of import and FDI related knowledge spillovers.  相似文献

In this study we investigate two reference dependence effects in a choice experiment. The first is the effect of the well-known distinction between gains and losses, the second is the effect of changing the reference value on willingness to pay (WTP) and willingness to accept (WTA). The latter has to our knowledge not been studied before. We hypothesize that there are differences between WTA and WTP, and that both value functions and their disparity are affected by the absolute value of the reference point. We test our hypotheses using a choice experiment with trade-offs between changes in flood probabilities and costs. The choice experiments elicit WTP and WTA, using two flood probability reference values, yielding four separate value functions. Our findings show that a substantial WTA–WTP disparity exists, and that this disparity increases when moving away from the reference point. Also, both WTA and WTP value functions are affected by the flood probability reference value, and the WTA–WTP disparity increases when the flood probability reference point increases. Both findings suggest that welfare effects caused by changes in public good provision depend not only on the direction of change (loss aversion), but also the reference value. Moreover, our results show that the latter effect is larger for losses than for gains. We introduce the concept of reference point updating as a possible explanation for these findings.  相似文献

How does the public react to changes in the stock market? We know from the existing body of research that sentiment can predict future stock-market movements. However, do market movements affect sentiment? This article addresses these questions by testing whether market movements precede changes in the emotional well-being of the general public. Using Granger causality analysis, we compare how market movements affect public well-being during periods of increased (2010) and decreased (2012) volatility. The results show that 30-day-lagged returns are associated positively and significantly with the public’s emotional well-being, and that this effect is stronger during periods of increased volatility. The results also show that this effect may persist for up to 120 days.  相似文献

Estimating two-step selection models, we find that more democratic governments are more likely to conclude preferential trade agreements (PTAs) and to agree to stricter investment provisions related to pre-establishment national treatment and investor–state dispute settlement in PTAs. This is surprising when considering the potentially high costs of litigation.  相似文献

We examine the impact of emission taxes on the pollution level in a duopoly framework with endogenous market structure. We demonstrate that an increase in emission taxes could trigger a regime switch from joint ventures to Cournot competition, causing the pollution level to increase. Such a phenomenon is likely to happen when the concerned industry is reasonably profitable, and the synergistic gain between joint venture partners is not too strong. Moreover, emission taxes can implement the first best outcome if and only if the industry is not too polluting. In case it is, the second best level of taxes may or may not equal the optimal tax under either joint venture or Cournot competition.  相似文献

In this endogenous growth model, a minimum efficient scale of production and workers’ home-to-work travel costs combine to give firms monopsony power, and this monopsony power leads to slower growth. Monopsony drives the wage below the marginal product of labor. This lower wage leads to lower investment in human capital and thereby to a lower growth rate. This makes investment in human capital – and therefore the growth rate – suboptimal. We provide evidence from a cross-country panel to support our model: Urbanization, which we assume is determined by a country’s exogenous population density and cropland area, positively impacts the wage share of output; the wage share positively impacts educational attainment; higher-income countries have higher wage shares; and within-country upticks in the wage share have a positive lagged effect on the growth rate.  相似文献

In this paper, we present the results of a unique time series analysis of contingent values and models for migratory bird protection based on an identical contingent valuation (CV) survey carried out over a three year time period since the first bird flu outbreak in 2003. Although there exists no scientific evidence for a direct relationship, migratory birds are believed to play an important role in spreading the bird flu virus worldwide. The time series analysis allows us to test the temporal stability of stated preferences for migratory bird protection and at the same time examine indirectly the possible impact of increased media attention and public awareness levels regarding the bird flu. We test the impact of the bird flu on public willingness to pay (WTP) for migratory bird protection in the final 2005 survey whilst accounting for procedural variance introduced by sequencing and question ordering-effects, but we are unable to demonstrate a direct negative relationship. A novelty of the study presented here is that respondents in the CV surveys are given the opportunity to pay an annual money amount or a one-time-off lump-sum. Annual WTP values appear to be significantly higher than one-time-off WTP values, suggesting a negative implicit discount rate. Self-selection bias is an important reason for the observed differences. We find that respondents who agree to pay annually differ significantly from respondents who wish to pay a lump-sum in terms of their underlying preferences and motivations towards migratory bird protection.  相似文献
